Release Notes

abseil/abseil-cpp (abseil-cpp)

v20250814.1: Abseil LTS branch, August 2025, Patch 1

Compare Source

Abseil LTS 2025081.1

What's New:

• absl::Mutex now contains lower-case method names like lock() and shared_lock() to align with standard C++ mutex methods. This allows absl::Mutex to be used with std::scoped_lock and friends. The old names are still present but may be removed in a future release.
• The RAII Mutex-locker types like absl::MutexLock, absl::ReaderMutexLock, and friends now accept references to absl::Mutex. The pointer-accepting constructors are now deprecated, and may be removed in a future release.

Breaking Changes:

• Nullability template types, which were deprecated in the May 2025 release, have been removed.
• absl::string_view(nullptr), which is undefined behavior according to the C++ standard, now triggers an assert failure. Note that unless you changed absl/base/options.h, absl::string_view is an alias for std::string_view, so by default you will be inheriting the behavior of your standard library instead of using the Abseil implementation.
• Abseil's hash tables now require a hash function that has a return type with size >= sizeof(size_t).

Baseline: 987c57f
Cherry-pick: d38452e (Patch 1)

Known Issues

• CHECK_<OP> is failing to compile on older versions of GCC when one of the arguments is a C-style string. This is fixed by ba9a180 and will be included in a future patch release.

v20250512.1: Abseil LTS branch, May 2025, Patch 1

Compare Source

Abseil LTS 2025051.1

What's New:

• The polyfill types absl::any, absl::optional, and absl::variant are now aliases for std::any, std::optional, and std::variant in all builds. (Note that the polyfill implementation absl::string_view remains at the present time, but it defaults to being an alias std::string_view in all builds.)
• Added absl::FastTypeId<Type>(), which evaluates at compile-time to a unique id for the passed-in type.
• Added absl::endian and absl::byteswap polyfills (25bce12).

Breaking Changes:

• Abseil now requires at least C++17 and follows Google's Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools.
• Nullability template types are deprecated and will be removed in a future release. The macro-style annotations (absl_nonnull, absl_nullable) should be used instead (caf854d).

Known Issues

• None known at this time.
